DEVICE FOR RETAINING LIQUID OR VISCOUS SUBSTANCES.

SPECIFICATION forming part Of Letters Patilt NO. 626,021; dated May 30, 1899.

Application filed February 1, 1899. Serial No. 704,132. (No model.)

To ctZZ whom it may concern:

Be it known that I, ANDREW H. GERDoM, a citizen of the United States of America, and a resident of the city of Albany, in the county of Albany, State of New York, have invented certain new and useful'lmprovements in Devices for Retaining Liquid or Viscous Sub-- Figure 1 is a plan showing the tube in condition for use. Fig. 2 is a plan, partly in section, showing the tube after a portion of its contents has been expelled. Fig. 3 is a-plan of the key. Fig. 4 is a section Fig. 5 is a plan of the metal strip before it is rolled into the form of a tube. Fig. 6 is a plan of Fig. 2 before the spout is compressed.

Similar letters refer to similar parts throughout the several views. 1;.

For the purpose of discharging paints; oils, or other viscous substances from tubes containin g the same it is customary to pinch the rear of the tube by squeezing the parts together, and thus causing the contents to be ejected through the port. This is often very difficult to accomplish.

In order to make it possible to discharge all of the contents from the tube and eject the same positively and at the expenditure of little force or strength, I have constructed a tube which may be in the form shown in the drawings or in any convenient from.

I preferably use a thin metal strip, one side of which is corrugated, as shown at B, and the ends of which are serrated, as shown at C O. I then secure the edges of the metal together by soldering, as shown in Fig. 6 at D, or unite-them in any suitable manner. I first arrange one side, WhichI call the back of the tube,which contains the corrugations B, and then'the other side or front of the tube, along which is the solder or uniting substance. The serrations O 0, Ipress together, forming a spout E. At the rear of the tube I arrange I attain this object by means of the an opening through which the key F may enter, and by means of which key I can wind the tube about itself, as shown in Fig. 2. It is apparent that the contents of the tube when the key is operated will be discharged through the spout E in quantities determined by the extent of the operation of the key.

The necessity of corrugating the tube along one side is apparent, because if both the front and rear of the tube were of the same length it would not Wind up smoothly, but would buckle and get out of shape. Making the corrugations along the back of the tube allows for the expansion necessary on that por= tion of the tube when winding about the key.

I sometimes place a cap A on the spout, as shown in Fig. 2, which may be done by threading the spout and meshing the threads in the cap.

I have illustrated the tube as made of one piece of metal. I may construct it of two or more pieces united together. I do not limit myself to the form of the key used or the cap.

It is apparent that the tube may be used for receiving not only oils, paints, and lubricating substances, but also for jellies, condensed milk, and various glutinous substances.

What I claim as my invention, and desire to secure by Letters Patent, is

l. A flexible tube provided with corrugations along one side thereof; a spout at one end; a key adapted to be inserted near the end of the tube opposite the spout, so arranged that by means of the key the tube may be wound about itself, substantially as described.

2. In a tube for retaining liquid or viscous substances, a corrugated portion along one side thereof; a spput; a cap adapted to be placed on said spout; a means for winding said tube from the rear end thereof upon itself, substantially as described.

3. A tube adapted to retain liquid or viscous ANDREW H. GERDOM.
